Any way to automatically add a css rule to external stylesheet from selected element in html editor?

Is there any way to select an element in the html editor (either an html element like a div, or an id or class) and have the program add an empty css rule to an attached external css file?

I can select elements using the "breadcrumbs" at the bottom of the editor window and they show in the Properties window, but there's no option to "create a rule for this [class or id or element] in my attached stylesheet."

I've seen instructions in the official help to open the "CSS Styles" window, but I have no option for a window of that name, only the "CSS Designer" window, which does not have any such functionality.

It seems like this would be useful instead of having to manually type all the selectors I want into my css file, but I can't figure out how to do it if it's even possible.

This is Dreamweaver 20.1 on Windows 10.
